[0023] Embodiment 1:

[0024] like Figure 1-3As shown, a construction dust reduction device includes a transport box 1, a spraying barrel 2 and a conduit 3. The spraying barrel 2 is arranged on the top of the transport box 1. The two ends of the conduit 3 are respectively connected with one end of the spraying barrel 2 and the top of the transport box 1 through an interlacing connection. A transport pipe 4 is arranged inside the conduit 3. A first disc 5 is sleeved on one end of the conduit 3. A second disc 7 is sleeved on one end of the transport pipe 4. A plurality of threaded holes 6 are provided on the surfaces of the first disc 5 and the second disc 7. The interiors of two adjacent threaded holes 6 are threadedly connected with limiting bolts 8. A diverter hood 9 is arranged inside the second disc 7. A plurality of flow holes 11 are provided on the inner wall of the diverter hood 9. The inside of the flow holes 11 are all fixedly connected with bellows 10, one end of each of the bellows 10 is provided with a guide tube 12, one end of each of the guide tubes 12 is provided with a flow disk 13, and the surface of each of the flow disks 13 is provided with a plurality of spray holes 14. The plurality of limiting bolts 8 are sequentially embedded into the inside of the corresponding two threaded holes 6 for threaded connection, so that the diverter hood 9 can be firmly limited to one end of the transport pipe 4, and the water transported inside the spray barrel 2 will continue to be guided to the inside of the guide tube 12 through the plurality of flow holes 11, and finally sprayed into the external environment along the position of one end of the diverter hood 9 and the plurality of spray holes 14.

[0025] Embodiment 2:

[0026] Based on the first embodiment, Figure 1 and Figure 4 As shown, the diameters of the multiple flow disks 13 are larger than the diameters of the multiple guide tubes 12, the positions of the multiple spray holes 14 are arranged at equal intervals, movable grooves are opened on both sides of the inner wall of the diverter hood 9, and moving blocks 16 are arranged inside the two movable grooves. Springs 15 are arranged on one side of the two moving blocks 16, and one end of the two springs 15 is fixedly connected to one side of the two movable grooves respectively. A support frame 17 is arranged between the inner walls of the two moving blocks 16. The utility model provides a construction dust reduction device, which is provided with a diverter hood 9, a spring 15, a moving block 16, a support frame 17 and a filter screen 18. After the water flow contacts the filter screen 18, it will drive the two moving blocks 16 to move in the movable groove in turn, and the spring 15 will gradually compress and deform.

[0027] Working principle: a water tank is placed inside the transport box 1, and the water tank is connected to the water pump through a valve, and the water tank is interlaced with one end of the conduit 3. When the water pump is started, the water in the water tank can be diverted to the inside of the conduit 3 and the spray barrel 2, and the water will continue to be diverted to one end of the spray barrel 2. At this time, the staff has already fitted one side of the second disc 7 with one side of the first disc 5, and successively embedded a plurality of limit bolts 8 into the corresponding two threaded holes 6 for threaded connection, so that the diverter cover 9 can be firmly limited to one end of the transport pipe 4. Originally, the water has been transported to the inside of the transport pipe 4 through the spray barrel 2. Since one end of the diverter cover 9 is fixed to the transport pipe 4, the water continues to be transported to the inside of the diverter cover 9. The water transported inside the diverter cover 9 will continue to be diverted to the inside of the guide pipe 12 through a plurality of flow holes 11, and finally as one end of the diverter cover 9 It is sprayed into the external environment at the position of multiple spray holes 14. Spraying with multiple spray holes 14 can achieve the effect of dust reduction at a higher position. Since the bellows 10 is a corrugated sheet connected along the folding and telescopic direction, the bellows 10 will gradually deform and swing under the force, thereby driving the guide tube 12 to shake under the impact of the water flow, and the spray holes 14 will continue to shake, the range of sprayed water will increase, and the working efficiency of the dust reduction device will be improved. After the water flow contacts the filter screen 18, it will drive the two moving blocks 16 to move in the inside of the movable groove in turn, and the spring 15 will gradually compress and deform, reducing the impact force of the water flow and the support frame 17, and improving the service life of the support frame 17 and the diverter cover 9. The filter screen 18 can filter foreign matter in the water to avoid foreign matter being directly sprayed onto the ground and increasing the labor intensity of cleaning.
